MIDDLEVILLE, MI — High levels of bacteria in Gun Lake at the Yankee Springs Recreation Area have prompted officials to close the beaches.

An E. coli test taken Monday from the lake rendered one result of more than 2,400, according to the Michigan Department of Environmental Quality. Levels of at least 300 E. coli per 100 ml are considered unsafe for body contact.

Additional tests taken Wednesday saw E. coli levels drop below 1,000. Officials test the lake's water three times a week.

The beaches at the recreation site have been closed since Wednesday. It is unclear what caused the sudden spike in bacteria levels.
